Does green entrepreneurship have an association with sustainable development and its components?
(IGI Global, 2022) Ajay K. Singh; Sanjeev Kumar; Aditya Kumar Sharma; Shivani Sinha
This study developed a global sustainable development index (GSDI), economic development index (EDI), social development index (SDI), environmental sustainability index (ESI), science and technological development index (STDI), entrepreneurship ecosystem index (EEI), and green entrepreneurship ecosystem index (GEI) for 34 countries during 2000-2019. Composite Z-score method was used to develop EDI, SDI, ESI, STDI, EEI, and GEI. It also observed the interaction among the estimated indexes using linear regression models. © 2022, IGI Global.

Forecasting global plastic production and microplastic emission using advanced optimised discrete grey model
(2023) Subhra Rajat Balabantaray; Pawan Kumar Singh; Alok Kumar Pandey; Bhartendu Kumar Chaturvedi; Aditya Kumar Sharma
Plastic pollution has become a prominent and pressing environmental concern within the realm of pollution. In recent times, microplastics have entered our ecosystem, especially in freshwater. In the contemporary global landscape, there exists a mounting apprehension surrounding the manifold environmental and public health issues that have emerged as a result of the substantial accumulation of microplastics. The objective of the current study is to employ an enhanced grey prediction model in order to forecast global plastic production and microplastic emissions. This study compared the accuracy level of the four grey prediction models, namely, EGM (1,1, α, θ), DGM (1,1), EGM (1,1), and DGM (1,1, α) models, to evaluate the accuracy levels. As per the estimation of the study, DGM (1,1, α) was found to be more suitable with higher accuracy levels to predict microplastic emission. The EGM (1,1, α, θ) model has slightly better accuracy than the DGM (1,1, α) model in predicting global plastic production. Various accuracy measurement tools (MAPE and RMSE) were used to determine the model's efficiency. There has been a gradual growth in both plastic production and microplastic emission. The current study using the DGM (1,1, α) model predicted that microplastic emission would be 1,084,018 by 2030. The present study aims to provide valuable insights for policymakers in formulating effective strategies to address the complex issues arising from the release of microplastics into the environment and the continuous production of plastic materials. © 2023.
